The cap member 54 includes cleavage portions 54c, 54c at positions corresponding to a boundary portion between the front portion 60 and the side portion 61 and a boundary portion between the front portion 60 and the side portion 62 of the upper portion 57b of the retainer 51. The cleavage portions 54c, 54c are groove portions provided in a rear surface of the cap member 54, for example.

As illustrated in FIG. 3, the airbag device 50 is supported by the vehicle body frame 10 by the retainer 51 being supported by and secured to the stay 14a.

The airbag device 50 is disposed such that the rectangular parallelepiped retainer 51 is inclined backward along an axial line 14b of the head pipe 14 in a side view of the vehicle. It is thus possible to compactly dispose the retainer 51 in front of the steering system 11.

Also, the upper portion 57b of the outer portion 57 is inclined backward in a side view of the vehicle, and the airbag 52 is deployed toward the rear upper side along the visor 39 and the wind screen 32 from the opening 63. The opening 63 is provided in substantially the same plane as the display surface 36a in front of the display surface 36a of the meter 36 disposed so as to be inclined toward the rear lower side, and is opened at a higher position than the display surface 36a.

Once gas is discharged from the inflator 53, the airbag 52 is expanded by the gas and is then deployed upward through the upper portion 57b of the outer portion 57 of the retainer 51. Once the airbag 52 expands, the cap member 54 is pushed and cleaved by the airbag 52, and the airbag 52 (see FIG. 1) is deployed from the opening 63 to the outer upper side. The cap member 54 is cleaved starting from the cleavage portions 54c, 54c.

Since the retainer 51 is disposed below the meter 36 in the embodiment, it is possible to compactly dispose the retainer 51 in front of the motorcycle 1. Also, since the opening 63 is provided so as to surround the meter 36 from the left and right sides and the front side, it is possible to satisfactorily deploy the airbag 52 upward from the opening 63 located in the surroundings of the meter 36 regardless of the configuration in which the retainer 51 is disposed below the meter 36.

Also, the airbag device 50 is provided above the head pipe 14 and is located near the upper body of the passenger from the head to the breast in the up-down direction. It is thus possible to appropriately protect the passenger even when the length of the airbag 52 in the up-down direction in a deployed state is reduced and thereby to reduce the size of the airbag device 50.
